how many countries in antarctica

[85], Emilio Marcos Palma was the first person born south of the 60th parallel south, the first born on the Antarctic mainland, and the only living human to be the first born on any continent. [36] Mercator Cooper landed in East Antarctica on 26 January 1853.[37]. Popular Quizzes Today. [180] Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent. There are a number of rivers and lakes in Antarctica, the longest river being the Onyx. This is a list of the countries of the world by continent, according to the United Nations Statistics Division, displayed with their respective national flags and capitals. East Antarctica is colder than its western counterpart because of its higher elevation. This is partly offset by autumn cooling in East Antarctica. Concerns have been raised that disruption of ice shelves may result in increased glacial outflow from the continental ice mass.[153]. Lake Vostok is the biggest lake at a length of 250 kilomet… This ice is formed from the ocean water and floats in the same water and thus does not contribute to rise in sea level. Even in the late 17th century, after explorers had found that South America and Australia were not part of the fabled "Antarctica", geographers believed that the continent was much larger than its actual size. [15], In the nineteenth century, the colonial authorities in Sydney removed the Dutch name from New Holland. It generally forms under otherwise clear or nearly clear skies, so people sometimes also refer to it as clear-sky precipitation. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. [167] The amount of surface warming in West Antarctica, while large, has not led to appreciable melting at the surface, and is not directly affecting the West Antarctic Ice Sheet's contribution to sea level. More than 50 Antarctic stations were established for the IGY by just 12 countries: Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norwa… It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. [92], Few terrestrial vertebrates live in Antarctica, and those that do are limited to the sub-Antarctic islands. Instead the recent increases in glacier outflow are believed to be due to an inflow of warm water from the deep ocean, just off the continental shelf. Motion of the ice sheet tends to concentrate the meteorites at blocking locations such as mountain ranges, with wind erosion bringing them to the surface after centuries beneath accumulated snowfall. There are currently 70 permanent research stations scattered across the continent of Antarctica, which represent 29 countries from every continent on Earth. [176], A study published in Nature Geoscience in 2013 identified central West Antarctica as one of the fastest-warming regions on Earth. The cooling of Antarctica occurred stepwise, as the continental spread changed the oceanic currents from longitudinal equator-to-pole temperature-equalising currents to latitudinal currents that preserved and accentuated latitude temperature differences. [31][32] The first recorded and confirmed landing was at Cape Adair in 1895 (by the Norwegian-Swedish whaling ship Antarctic). Models of the changes suggest that declining CO2 levels became more important. The flightless midge Belgica antarctica, up to 6 mm (1⁄4 in) in size, is the largest purely terrestrial animal in Antarctica. If the sheet were to break down, ocean levels would rise by several metres in a relatively geologically short period of time, perhaps a matter of centuries. [142], In September 2006 NASA satellite data revealed that the Antarctic ozone hole was larger than at any other time on record, at 2,750,000 km2 (1,060,000 sq mi). Currently, the Polar Geospatial Center can image all of Antarctica at 500 mm (20 in) resolution every 45 days. [57][58] On 7 February 2008, a NASA team embarked on a mission to Lake Untersee, searching for extremophiles in its highly alkaline waters. [146], A study from 2014 estimated that during the Pleistocene, the East Antarctic Ice Sheet (EAIS) thinned by at least 500 m (1,600 ft), and that thinning since the Last Glacial Maximum for the EAIS area is less than 50 m (160 ft) and probably started after c. 14 ka. There is no universally accepted answer as to how many countries in the world there actually are. As a result of continued warming, the polar ice caps melted and much of Gondwana became a desert. The three main stipulations surrounding Antarctic land use: Antarctica's goal is for minimal human-derived human impacts and for researchers to leave no trace. Antarctica is Earth's southernmost continent. Costing $16.3 million, the prefabricated station, which is part of the International Polar Year, was shipped to the South Pole from Belgium by the end of 2008 to monitor the health of the polar regions. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. Gamburtsev Mountain ranges is a chain of mountains almost the size of the Alps but are buried by the ice. Integral to the story of the origin of Antarctica's name is that it was not named Terra Australis—this name was given to Australia instead, because of the misconception that no significant landmass could exist further south. About Countryflags.com The main mineral resource known on the continent is coal. There are approximately 50 permanent active research stations representing 32 countries drawn from all the continents. Next to the continental shore are many ice shelves. Most of these meteorites have fallen onto the ice sheet in the last million years. If all of this ice were melted, sea levels would rise about 60 m (200 ft). It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling. [99], About 1,150 species of fungi have been recorded from Antarctica, of which about 750 are non-lichen-forming and 400 are lichen-forming. [20], European maps continued to show this hypothetical land until Captain James Cook's ships, HMS Resolution and Adventure, crossed the Antarctic Circle on 17 January 1773, in December 1773 and again in January 1774. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year. [21] Cook came within about 120 km (75 mi) of the Antarctic coast before retreating in the face of field ice in January 1773.[22]. [181] In 2019, the ozone hole was at its smallest in the previous thirty years, due to the warmer polar stratosphere weakening the polar vortex. [33], On 22 January 1840, two days after the discovery of the coast west of the Balleny Islands, some members of the crew of the 1837–40 expedition of Jules Dumont d'Urville disembarked on the highest islet[34] of a group of coastal rocky islands about 4 km from Cape Géodésie on the coast of Adélie Land where they took some mineral, algae, and animal samples, erected the French flag and claimed French sovereignty over the territory.[35]. While there are no countries in Antarctica, there are several territories. Glaciologists in Antarctica are concerned with the study of the history and dynamics of floating ice, seasonal snow, glaciers, and ice sheets. She was a daughter of Fridthjof Jacobsen, the assistant manager of the whaling station, and Klara Olette Jacobsen. [148], This large collection of meteorites allows a better understanding of the abundance of meteorite types in the solar system and how meteorites relate to asteroids and comets. [7] The temperature in Antarctica has reached −89.2 °C (−128.6 °F) (or even −94.7 °C (−135.8 °F) as measured from space[8]), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). The apparently simple morphology, scarcely differentiated structures, metabolic systems and enzymes still active at very low temperatures, and reduced life cycles shown by such fungi make them particularly suited to harsh environments such as the McMurdo Dry Valleys. Rate 5 stars Rate 4 stars Rate 3 stars Rate 2 stars Rate 1 star . It has since been agreed to by many other nations. However, it is the outflow of the ice from the land to form the ice shelf which causes a rise in global sea level. He who owns the information, owns the world – said V.Cherchill. [142], In 2007 The Polar Geospatial Center was founded. In Eastern Antarctica, seed ferns or pteridosperms became abundant and large amounts of sandstone and shale were laid down at this time. At 14,200,000 square kilometres (5,500,000 square miles), it is the fifth-largest continent and nearly twice the size of Australia. The claims of Britain, Australia, New Zealand, France and Norway are all recognised by each other. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. [1], Although coal, hydrocarbons, iron ore, platinum, copper, chromium, nickel, gold and other minerals have been found, they have not been in large enough quantities to exploit. During the Eocene–Oligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm[67] and had been decreasing from earlier levels in the thousands of ppm. Related Searches. [165] There is evidence from one study that Antarctica is warming as a result of human carbon dioxide emissions,[166] but this remains ambiguous. [11] Marinus of Tyre reportedly used the name in his unpreserved world map from the 2nd century CE. The treaty states that all parties involved agree that Antarctica shall forever to be used exclusively for peaceful purposes. No country owns Antarctica, although several countries have claimed parts of it. Seven nations have made claims in Antarctica, but about 30 of the countries that have signed the Antarctic Treaty send personnel to research stations on the Antarctic continent and the Antarctic Peninsula. A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may be influenced by ground temperatures and was not recorded at a height of 7 feet (2 m) above the surface as required for the official air temperature records. Glaciation began at the end of the Devonian period (360 Ma), as Gondwana became centred on the South Pole and the climate cooled, though flora remained. This study also noted that West Antarctica has warmed by more than 0.1 °C (0.2 °F) per decade in the last 50 years, and this warming is strongest in winter and spring. Seven countries have laid claim to parts of Antarctica and many more have a presence there - why is this frozen wasteland so desirable? In 1969, a Japanese expedition discovered nine meteorites. This list of all countries in Antarctica is actually a list of the countries that have claimed territory in Antarctica with the names of the Antarctic territories. [182], Some scientific studies suggest that ozone depletion may have a dominant role in governing climatic change in Antarctica (and a wider area of the Southern Hemisphere). However, belief in the existence of a Terra Australis—a vast continent in the far south of the globe to "balance" the northern lands of Europe, Asia and North Africa—had prevailed since the times of Ptolemy in the 1st century AD. [1], The ISO 3166-1 alpha-2 "AQ" is assigned to the entire continent regardless of jurisdiction. [1] McMurdo Station, which is the largest research station in Antarctica, is capable of housing more than 1,000 scientists, visitors, and tourists. The continent, however, remained largely neglected for the rest of the 19th century because of its hostile environment, lack of easily accessible resources, and isolation. [118] In 1988, the Convention on the Regulation of Antarctic Mineral Resources (CRAMRA) was adopted. Most of the whalers were Norwegian, with an increasing proportion of Britons. Towards the end of the Permian period, continued warming led to a dry, hot climate over much of Gondwana.[62]. It was never colonized due to the harsh climate and conditions, so the land remained open and free from claim disputes. [127][128], There is no economic activity in Antarctica at present, except for fishing off the coast and small-scale tourism, both based outside Antarctica. In 1985, three British scientists working on data they had gathered at Halley Station on the Brunt Ice Shelf discovered the existence of a hole in this layer. On top of this base are coal and various modern rocks, such as sandstones, limestones and shales laid down during the Devonian and Jurassic periods to form the Transantarctic Mountains. The Polar Geospatial Center uses geospatial and remote sensing technology to provide mapping services to American federally funded research teams. Military personnel or equipment are permitted only for scientific research or other peaceful purposes. The countries of Argentina, Australia, Chile, United Kingdom, Norway, France, and New Zealand have made claims to the continent of Antarctica. Researchers include biologists, geologists, oceanographers, physicists, astronomers, glaciologists, and meteorologists. In the summer more than 4,000 scientists operate research stations; this number decreases to just over 1,000 in the winter. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. [126], Other countries participating as members of the Antarctic Treaty have a territorial interest in Antarctica, but the provisions of the Treaty do not allow them to make their claims while it is in force. Robertson Land, Wilkes Land, and Victoria Land. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. All but a small portion of this region lies within the Eastern Hemisphere. Antarctic sightseeing flights (which did not land) operated out of Australia and New Zealand until the fatal crash of Air New Zealand Flight 901 in 1979 on Mount Erebus, which killed all 257 aboard. King penguins, chinstrap penguins, and gentoo penguins also breed in the Antarctic.

While there are no countries in Antarctica, there are several territories. Today, seven countries have territories on Antarctica: France (Adélie Land) United Kingdom (British Antarctic Territory) New Zealand (Ross Dependency) Antarctica (/ænˈtɑːrtɪkə/ or /æntˈɑːrktɪkə/ (listen))[note 1] is Earth's southernmost continent. [46], On 28 November 1979, Air New Zealand Flight 901, a McDonnell Douglas DC-10-30, crashed into Mount Erebus, killing all 257 people on board. Sheperd et al. [155] The same group's 2018 systematic review study estimated that ice loss across the entire continent was 43 gigatonnes per year on average during the period from 1992 to 2002 but has accelerated to an average of 220 gigatonnes per year during the five years from 2012 to 2017. Together, these countries, or ‘signatories’ of the Antarctic Treaty, must ensure the preservation and wellbeing of the natural land, and to cooperate with their fel… Astrophysicists at Amundsen–Scott South Pole Station study the celestial dome and cosmic microwave background radiation. As a result, the continental mass of the East Antarctic ice sheet is held at lower temperatures, and the peripheral areas of Antarctica, especially the Antarctic Peninsula, are subject to higher temperatures, which promote accelerated melting. This sediment uplift was accompanied by igneous intrusions and volcanism. It used to be ice-free until about 34 million years ago, when it became covered with ice. [97] The southern rockhopper penguin has distinctive feathers around the eyes, giving the appearance of elaborate eyelashes. Solved: How many countries are on the Antarctica continent? [105] Growth is restricted to a few weeks in the summer. As a result, the diversity of plant life is very low and limited in distribution. East Antarctica lies on the Indian Ocean side of the Transantarctic Mountains and comprises Coats Land, Queen Maud Land, Enderby Land, Mac. This area is dominated by small accumulations of snowfall which becomes ice and thus eventually seaward glacial flows. Synapsids, commonly known as "mammal-like reptiles", were common in Antarctica during the Early Triassic and included forms such as Lystrosaurus. [109][110], Several countries claim sovereignty in certain regions. In the interior, wind speeds are typically moderate. Regarded as the “international continent”, Antarctica is a place of worldwide cooperation, peace, and scientific discovery. Travel is largely by small or medium ship, focusing on specific scenic locations with accessible concentrations of iconic wildlife. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. [100][101] Some of these species are cryptoendoliths as a result of evolution under extreme conditions, and have significantly contributed to shaping the impressive rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. At a number of points in its long history, it was farther north, experienced a tropical or temperate climate, was covered in forests,[61] and inhabited by various ancient life forms. Antarctica is the coldest continent in the world, completely covered with ice. The latter in its brief sojourn actually made a temporary landing; while the Wilkes expedition, though it did not make a landing, did remain long enough in the region to survey and map some 800 miles of the continent. The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), a treaty that came into force in 1980, requires that regulations managing all Southern Ocean fisheries consider potential effects on the entire Antarctic ecosystem. In 1895, the first confirmed landing was conducted by a team of Norwegians. Read more on the Southern Ocean here. Antarctica will remain to be used as intended for research and as a nature reserve. [100][106], Seven hundred species of algae exist, most of which are phytoplankton. The frozen surface of the lake shares similarities with Jupiter's moon Europa. Richard E. Byrd led several voyages to the Antarctic by plane in the 1930s and 1940s. Many countries conducted their first Antarctic explorations and constructed the first research stations on Antarctica. [64] It was during this era that Gondwana began to break up. However, there are a number of research stations, each of which observes its own local time. It is roughly the size of the United States and Mexico combined and is almost completely covered by a layer of ice that averages more than one mile in thickness, but is nearly three miles thick in places. Recent decades have witnessed several dramatic collapses of large ice shelves around the coast of Antarctica, especially along the Antarctic Peninsula. Due to its location at the South Pole, Antarctica receives relatively little solar radiation except along the southern summer. He is credited with implementing mechanised land transport on the continent and conducting extensive geological and biological research. The first meteorite was found in 1912 and named the Adelie Land meteorite. Qantas resumed commercial overflights to Antarctica from Australia in the mid-1990s. Dozens of research stations, some year-round and others seasonal, operate in Antarctica under the guidance of around 30 individual countries. [171] Between 28 February and 8 March 2008, about 570 km2 (220 sq mi) of ice from the Wilkins Ice Shelf on the southwest part of the peninsula collapsed, putting the remaining 15,000 km2 (5,800 sq mi) of the ice shelf at risk. During the whaling era, which lasted until 1966, the population of that island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. Most countries have a research center in Antarctica within the area claimed by them. [78][79] Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. Antarctica is the southernmost continent on Earth. Medical physicians have made discoveries concerning the spreading of viruses and the body's response to extreme seasonal temperatures. In January 1840, terra firma at Antarctica was discovered for the first time, almost simultaneously, by the United States Exploring Expedition, under Lieut. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. There has been some concern over the potential adverse environmental and ecosystem effects caused by the influx of visitors. [17], Antarctica has no indigenous population. The member states of the United Nations (UN). More surprising are small forms of life such as sea cucumbers and free-swimming snails found in both polar oceans. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. Sand and silts were laid down in what is now the Ellsworth, Horlick and Pensacola Mountains. Some of these claims are recognised by other countries, but many aren’t. [162][164], Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. Sea ice extent expands annually in the Antarctic winter and most of this ice melts in the summer. Charles Wilkes, and a separate French expedition under Jules Dumont d'Urville. [106] Bacteria have been found living in the cold and dark as deep as 800 m (0.50 mi; 2,600 ft) under the ice. Explorer Matthew Flinders, in particular, has been credited with popularising the transfer of the name Terra Australis to Australia. During that period, geographers had to make do with clumsy phrases such as "the Antarctic Continent". The IGY prompted an intense period of scientific research in the Antarctic. The treaty prohibits military activities and mineral mining, prohibits nuclear explosions and nuclear waste disposal, supports scientific research, and protects the continent's ecology. Aboa: Finland: 73°03'S 013°25'W: Queen Maud Land: 400 m : 1989 In West Antarctica, coniferous forests dominated through the entire Cretaceous period (146–66 Ma), though southern beech became more prominent towards the end of this period. Fortunately for polar enthusiasts, there are no cities on the Antarctic continent –only stations. No, it does not. The Argentine, British and Chilean claims all overlap, and have caused friction. [14], The long-imagined (but undiscovered) south polar continent was originally called Terra Australis, sometimes shortened to Australia as seen in a woodcut illustration titled "Sphere of the winds", contained in an astrological textbook published in Frankfurt in 1545. In 1983 the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. The illegal fishing of toothfish has been increasing, with estimates of 32,000 tonnes (35,000 short tons) in 2000. Multicoloured snow algae and diatoms are especially abundant in the coastal regions during the summer. [75] For comparison, this is 10.7 °C (20 °F) colder than subliming dry ice at one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than −140 °C (−220 °F)[76] would be needed to produce dry ice snow in Antarctica. By 1959, 12 countries came together to create the 1959 Antarctica Treaty: Argentina, Australia, Belgium, Chile, the French Republic, Japan, New Zealand, Norway, the Union of South Africa, the Union of the Soviet Socialist Republics, the United Kingdom of Great Britain and Northern Ireland, and the United States. This hole covers almost the whole continent and was at its largest in September 2008, when the longest lasting hole on record remained until the end of December. [52] This ice sheet is constantly gaining ice from snowfall and losing ice through outflow to the sea. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment.
